Ok this is my first one I don't know what I'm doing
I found a 6 foot pipe that is used for making the roll cage
In dragsters it not that thick of walled. Will not hold a set screw
But will hold the zerks. So I welded on some nuts to hold set screws.
It just going to be a 7hp longtail should I use the tube or
Find somthing thicker. How tuff should the outer house be.

thats for the shaft housing?? i definitely would go thicker. even if you only have 7hp, the impact is still high when you hit something. just my .02

Best to use dom tube

It still DOM tube I fig you SS shaft would take most
Of the force if you hit somthing. No ?

the shaft transfers all of the upward shock through the bushings and into the tube, not to mention steering forces and some of the thrust load. I wouldnt go thin on the shaft tube, it will probably bend
